n. A Strategic Party Nap (SPN) is a nap that is strategically taken before you start your night of partying. Obviously you are going to rage hard, and in preparation, you need to restore some energy from your hard days work.

Alex: "Dude! Just take a strategic party nap and then we can rage all night long"
